Description

Technical Field

[0001] The present invention relates to the technical field of wheelchairs, and in particular to a multifunctional wheelchair for patients. Background Art

[0002] Patients who have difficulty walking need to use a wheelchair when going out for examinations or activities. However, when it rains or is sunny, the patient's body will get wet and easily catch a cold, or if they are exposed to the sun for too long, they will suffer from glare, dizziness and other discomforts.

[0003] The utility model patent with patent application publication number CN206560506U discloses a wheelchair with sunshade and rainproof functions, including a support plate, a driving wheel and an auxiliary plate are provided at the bottom end of the support plate, the driving wheel is located on one side of the auxiliary plate, the driving wheel is installed at the bottom end of the support plate through a bracket, and a driven wheel is provided at the bottom end of the auxiliary plate. The utility model is provided with a backrest box on the support plate, a frame and a sunshade tarpaulin are provided in the backrest box, movable rods are provided on both sides of the frame, and a groove is provided on the inner wall of the backrest box, so that the sunshade tarpaulin can be quickly installed and folded to prevent the sunshade tarpaulin from being inconvenient to carry and blocking the line of sight when not in use. The sunshade tarpaulin includes a first shielding cloth, a second shielding cloth and a third shielding cloth. When shading, the second shielding cloth and the third shielding cloth can be folded.

[0004] The above wheelchair can achieve a certain sunshade and rainproof effect, but there are still some shortcomings in actual use. For example, its sunshade and rain cloth can only block the upper part of the patient when shielding, but cannot effectively block the sunlight and rain from the side, so it will still cause the patient to get wet in the rain and feel dizzy and uncomfortable due to excessive sun exposure. Secondly, the angle of the wheelchair backboard cannot be adjusted, and the user can only sit. If the patient is very weak and wants to lie half-lying or lying down, it cannot be achieved, and the scope of application is small.
